How would you feel if, every time you had to send sensitive information somewhere, you relied on a chain of people playing the telephone game to get that information to where it needs to go? Sounds like a terrible idea, right? Well, too bad, because that’s how the Internet works.
Data is routed through the Internet’s various metaphorical tubes using what’s called the Border Gateway Protocol (BGP). Any data moving over the Internet needs a physical path of networks and routers to make it from A to B. BGP is the protocol that moves information through those paths—though the downside, like a person in a game of telephone, is that each junction in the path only knows what they’ve been told by their immediate neighbor.
